Summary

Table. Summary of the 2024 Trinity Ledge spawning ground acoustic survey data and associated biomass estimates. A maximum biomass estimate value is taken when that are less than 10 days, instead, a single value is used in the reported biomass estimates for 10 day intervals.

Summary

Table. Summary of the 2024 Eastern Shore spawning ground acoustic survey data and associated biomass estimates. A maximum biomass estimate value is taken when that are less than 10 days, instead, a single value is used in the reported biomass estimates for 10 day intervals.

Length Frequency

Figure. Length distribution used for calculation of TS for the Eastern Shore acoustic surveys with proportions <23cm and >30cm shown as white and grey bars.

Maturity Samples

Figure. Herring maturity samples collected during Eastern Shore surveys in 2024 to determine proportion of individuals spawning for Eastern Shore acoustic index of spawning stock biomass. Stage codes are: 1-2 Immature, 3-5 Ripening or Ripe. 6, Spawning, 7 Spent, and 8-9 Recovering.
